CompSniper
For resellers and flippers

Know what it sold for
before you buy it

Sourcing at a thrift store, an estate sale, or a storage auction, you have seconds to decide. CompSniper puts the last 240 real eBay sales for any item in your hands so you buy on data, not on a gut feeling about what something might be worth.

100 free requests every month. No credit card required.

The problem

Manual comps do not scale

Searching eBay by hand, filtering to sold, and eyeballing an average works for one item. It falls apart the moment you are pricing a cart full of finds or feeding numbers into a spreadsheet or app.

  • eBay's sold filter caps out fast and buries condition, shipping, and offer details you actually need.
  • Averaging ten listings in your head at a garage sale is slow and error prone.
  • Copy-pasting prices into a spreadsheet item by item eats the margin you came for.
  • Third-party lookup tools guess with estimates instead of real completed transactions.
How it works

From keyword to data in three steps

01

Send the keyword

One GET request with your item's keyword, exactly how you would type it into eBay search. Add price, condition, or date filters if you want to narrow it.

02

We pull the sold listings

We fetch the real completed sales from eBay and parse every field so you never touch HTML, proxies, or pagination.

03

You price with confidence

Get back up to 240 sold comps as clean JSON. Compute a median, spot the condition premium, and set your buy price in seconds.

Example

Why it works for you

Built to make this job faster

Decide in seconds, not minutes

A median from 240 real sales beats scrolling eBay by hand. Make the buy while you are still standing at the table.

See the condition premium

Every comp carries its condition label and ID, so you can tell a complete boxed set apart from a loose lot at a glance.

Shipping-inclusive totals

Sold price, shipping cost, and total price come separate, so your margin math reflects what buyers actually paid.

Price a whole cart at once

Loop your finds through the endpoint and get a valuation for every item without a single manual search.
